MEANS FOR OPERATING DRIVEN MECHANISMS.

Specification of Letters Patent.

Patented Jan. 30, 1917.

Original application filed December 7, 1914, Serial No. 875,860.Divided. and this application filed April 5-,

To all whom it may concern:

Be it known that I, Ronnn'r T. JENNEY, a citizen of the United States,and a resident of Monticello, in the county of Jones and State of Iowa,have invented a new and useful Means for Operating Driven Mechanisms, ofwhich the following is a specification.

The invention relates to friction-clutches, to the. means for operatingthem, and to mechanism operable by or from the clutch members.

The primary object of the invention is to generally improve theconstruction and to increase the capacity, utility and efiiciency ofdevices of the same or a similar nature.

Other objects will presently appear. Some of these will be obvious andothers will be specifically pointed out.

The invention consists, substantially, in the constructions andcombinations shown in the accompanying drawings and herein described.

The above noted objects I attain by means, a preferred form of which isillustrated in said drawings, said form being identical with that shownand described in my c0- pending application, filed December 7, 1914, No.875,860, for patent for corn-husker, ensilage-cutter, and silo-filler,of which the present application is a division.

It is to be understood, however, that while I have in the foregoingnamed application shown the herein described improvements in connectionwith Or embodied in a machine for performing certain operations on corn,the herein described means is applicable to any mechanism with which itmay be operatively connected.

In the drawings above referred to: Figure l is a top plan; Fig. 2, anenlarged sectional I detail, partly in elevation; Fig. 3, an enlargedend detail, the pulley 9 removed and the shaft portion 6 shown insection; and Fig. 1, a detail of the yoke.

The exact construction of the preferred form of my improvements will bedescribed in full herein, but I do not intend by describing the detailsthereof to be understood as limiting my claims in any way or mannerthereto, the scope of the invention being pointed out in the claimshereto appended.

Considering the drawings in detail, and referring to each element and,where required, to each part thereof, by a distin-' Serial No. 19,386.

guishing numeral, uniformly employed, 22 indicate frame-bars which, itmay be assumed, are parts of any suitable machine.

3 indicates a drive shaft mounted in bearings a secured by bolts 5 tosaid bars 2. One of its end portions is reduced or constructed, asindicated at 6.

7 designates the drive-pulley fixed on and driving said shaft, and 8designates the drive-belt embracing said pulley and driven from anysuitable source of power.

9 indicates a driven pulley constitutingone member of a frictionclutchpresently more fully described. It is fixed by a key 10 on theconstricted portion 6 of the shaft 3. The internal. and, relatively tothe frame, inner face of its rim is beveled or flared, as clearly shownin Fig. 2.

On the reduced portion of the shaft 3 and bearing against the. shoulder11 provided by reducing its end portion 6 is rotatively mounted a pinion12 which is integral with an elongated sleeve 13 to which is secured bya spline 1d a friction-clutch head 15 the neck of which is provided withan annular groove 16. F riction-shoes 17 having each a beveled androunded face 18 adapted to conform to the contour of and to frictionally engage the beveled. and rounded inner face of the rim of the pulley9, are secured by bolts 19 and nuts 20 to the head 15.

20--20 indicate slots, one in the outer end portion of each of the armsof the head 15, and are adapted for the reception of the bolts 19,whereby the shoes 17 may be adi'usted relatively to the flange of thepul- 2121 designate adjusting screws, threaded each through and engagingthe threads of a boss 22 and adapted to bear against the shoes 17.

23 indicates an expansion spring encir- 31 indicates a link crossing theframe 2 and pivotally connected at its ends to the shift lever 27 andbell crank 29.

32 designates a driven shaft mounted in bearings 36 secured by bolts 35to the frame bars 2.

33 represents 'a spur gear wheel fixed on said shaft 32, and 34indicates a s rocket or other wheel fixed on the same sha t. The wheel34: is merely illustrative, and any other medium for transmitting motionfrom the shaft 32 may be substituted therefor.

Assume the parts to be in the relative positions shown in Figs. 1 and 2,in which the shoes 17 are in frictional engagement with the beveledconcave face of the rim of the pulley or belt-wheel 9 and the wheels 12and 33 in mesh. In this position the shaft 3 will transmit motion to thebelt-wheel 9 (from which a driving-belt may be actuated) and the pinion12 will drive the spur 33 and thereby the shaft 32 and wheel 34.

In order to stop the rotation of the wheel 9 the operator will throw thelever 29 to the dotted line position indicated in Fig. 1 to draw on thelink 31 and thereby cause the lever 27 and collar 26 (through the mediumof the pins 25) to shift the yoke 24: inwardly, to thereby retract thehead 15 and shoes 17 in the same direction, overcoming the resistance ofthe spring 23 and withdrawing said shoes from their frictionalengagement with the rim of the wheel 9. The portion 6 of the shaft 3will revolve freely in the bore of the sleeve 13, and the movement ofthe pinion 12 will cease, thereby stopping the movement of the wheels 33and 34 and the shaft 32, and, of course, any mechanism driven thereby.

The shoes 17 may be adjusted toward or from the inner face of the rim ofthe wheel 9 by suitable adjustments of the screws 21, and after suchadjustments they may be locked by means of the bolts 19 and nuts 20. Bymoving the lever 29 but a short distance the shoes 17 will be drawn butslightly from the rim of the wheel 9, and the shoes will then act as abrake. It will be understood, of course. that any other driving meansmay be substituted for the belt-wheel 9 or the pinion 12, and that otherdriven mechanism may be substituted for the wheels 33 and 34 and theshaft 32.
